Automatically Rename Last Generated File
I'm trying to rename the last generated file in a given directory using a makefile.
If I type 'make build' the 'build' target produces a file (ie: text_001.txt). It automatically generates them sequentially, so I don't have control over the name. I can't say that it will always be text_001.txt. Otherwise it would be easy:
mv text_001.txt build.txt
I would like to take the last generated .txt file and rename it ... something like: build.txt. Since I'm setting this up for other users however, I want to script this behavior. I know how to get the latest file by doing an ls -t *.txt, but I don't know how to (a) automatically find the latest file and (b) then rename that file.
I could do this using a perl script, but I would think it can be done much faster. Something like:
find . -name *.txt exec mv {} ...
Can anyone help?
